Hi,

I have Kura 3.2.0 installed on my Rpi.

I want to send messages generated from opcua_demo_server
to AWS IoT hub. I've been following the guide at:

https://eclipse.github.io/kura/cloud/kura-aws-cloud.html

Of course I've taken into account the 3.2.0 note but despite that the MQTT connection to AWS does not work and i receive the following error: bad certificate

Care to help me out?

Michele

Hi,
could you please provide the content of kura.log and kura-console.log?
Could you also double check, using keytool, that the certificate is actually in the keystore?

Thanks.
Best regards,
Matteo

The error generated whenever I click on connect to AWS on the Cloud Connection tab:

Hi all,

i trying out Kura 3.2.0 with AWS right now and i am experiencing exactly the same problem as described in the opening post.

Can anybody confirm this is an official issue or the other way round, that AWS CloudConnection is definitely working on Kura 3.2.0

I am using Pi 3b+
the keystore contains 2 keys, one of type trustedCertEntry from verisign and one of AWS of type PrivateKeyEntry.

Kind regards,
Hans

Hi,
is the certificate signature the same between the files you are using and the certificate loaded in the keystore?

Best regards,
Matteo
